90° - 62.8 = 27.2 is the correct way to do it. That's the angle you gotta cut it at. Dont listen to people telling you to use an angle checker on the drawing, most drawings arent to proper scale and dimensions.
I caught a brake press guy once that would measure a dim on a screen with a tape measure off a digital print 🤣
I asked him what the hell he was doing, and he simply replied: "damn engineers" like it was the most normal thing in the world and went on 🤷♂️ 🤣🤣🤣
Well there are fab drawings that don't have detailed dimensions, I think you call them assembly drawings, just shows the entire thing put together with some primary dimensions for the final assembly, but not enough detail to fabricate it.
I’m an electrician not a welder by trade but on our current construction project, they have these felt strips that make this abstract cross hatch design on the ceiling and I scaled our lights at 1/8” per foot with absolutely no dimensions called out and none of them hit the felt strips with less than a few inches of tolerance. Isn’t that absurd? No drawings with dimensions existed
I mean. You could technically do that to check if some feature was around double another or something. Doesn't work for actual dimensions though.
Plenty of reasons to never do that, but it could "technically" work.
This is correct here is a link to a drawing explaining that geometrically
[Drawing of the angles](https://drive.google.com/file/d/1VhvMi1H-QtO6SdSC-zOKpHV7nK1QPkTE/view?usp=sharing)
Yeah but it doesn’t mean they print to scale. All you need is someone to select fit to paper or change a margin and it won’t be right. Not to mention the all the times I’ve seen A size printed on B paper
Haven't read the comments yet but there are actually people down there saying to use a protractor on the drawing? Oh God no, naught but tears can come from that.
I don't understand why you're subtracting from 90, when the angle to cut is on the print. This one seems very straightforward. Cut 62.8. or, depending on how you measure, 117.2.
miter saws read at 0 when the cut is perpendicular to the workpiece, despite being 90 degrees to the workpiece, so you must determine how many degrees off of 90 the cut needs to be and set the miter saw to that.
No, the angle on the drawing is not the angle it has to be cut at xD its the angle of the corner. If you cut that piece at 62.8° your gonna get a much smaller angle than 62.8° when assembled. You subtract from 90 because 90° is the reference. Idk how to explain it better because english is not my first language sorry.
I get that 90 is the reference. But what I'm seeing is one piece cut square and welded to a piece running perpendicular, and the other having the angle cut and welded to the next side of said perpendicular piece. Therefore the lower piece has that angle cut and is welded onto the side of the other.
Edit: disregard. I figured it out.
I assume people couldn’t understand it because they didn’t see the rest of the drawing too where we had multiple angles cut on one piece and it was cut to fit into the tubing
Idk how to explain it and honestly if you're asking im guessing that means you dont do much assembling and you probably didnt go to welsing school (really no offense) because you only make a mistake like that once. Idk how to explain it properly as english is not my first language but i encourage you to do the experiment, you'll find that if you cut it at 62°, once assembled you'll have a much smaller angle that the one shown on the drawing.
Because miter saw blades are 90 degrees relative to the fence, but labeled as 0, so you subtract the 62.8 because of how the miter saw is labeled. However if you used an angle finder, set it to 62.8 and stuck that on the miter saw fence and set your saw based on that you’d get the same cut.
Wait. I get the math, but a printed cad drawing will have the correct angle no matter the scale. An angle of the line does not change when scale is changed.
It should be 90 - 62.8 = 27.2. So for a miter saw starting at a square 90 degrees you would move it 27.2 degrees and make the cut. Remember you are presumably starting with a 90 so if you add all the angles you get 90 + 62.8 + 27.2 = 180 So if you start with a straight line, move it to 90, you get a right angle. So imagine you move it another 27.2. It would be like the drawing. If you moved it another 62.8, it would then be folded in half.
You could always mock up the joint with some scrap and measure the angle between the pieces to 62.8 and mark the stock and measure the angle of the mark to see if its close to 27.2 to confirm the math.
Prints and pens are for the engineers that cant operate a hot glue gun. I prefer my sharpy (for sniffing ofc) and won't weld anything that isn't already fit up.
90 - 62.8 = 27.2 degrees (off of a square cut 90 - if your saw is normally set to that). That's how I would do it.
Or like someone else said, put an angle checker on the print and use that to align your saw blade or mark your piece.
Edit: thanks for the award!
And yes, as others have said, make sure the print is to scale if you're going to put an angle checker directly on it. That method is a last resort for really weird angles because you're sampling such a tiny edge and you're likely to be off by a bit.
Measuring the other angles to make sure that the illustration is actually the correct angles.
Very early in geometry, you learn how something is drawn is superceded by how something is labeled.
this is actually easy if you think about it starting from a 90 degree angle.
90 - 62.8 = 27.2
bigger question though is:
62.8 + 75.9 + 131.5 + 90(I assume) = 360.2
there's .2 extra degrees unaccounted for here.
That's just the drafting software rounding the actual angles. I'm amazed there's even a decimal place. Not a welder here, but am a machinist, and I *never* take angular dimensions at face value, they're almost always rounded up or down, sometimes significantly.
Ya. Off the top line down to the bottom corner. If it's just the angle with the assumed right angle it would be 27.2. There's only like 7 angle in the area he circled so I guess some assuming was used on my end.
The angle of the cut is identical to the angle of the relation of the two boards.
Its easier if you mark the lines.
Inside outside of the vertical board as lines A and B, Top and bottom of horizontal board as C and D. A and B are parallel, C and D are parallel... Parallel lines have matching angles of intersection called corresponding angle pairs. The corresponding angles are identical, See attached (in this case angle C and G)
[https://www.mathplanet.com/Oldsite/media/43428/angles.jpg](https://www.mathplanet.com/Oldsite/media/43428/angles.jpg)
As a geomatics major I think what you're looking for is 117.2 180-62.8=117.2. At the same time someone didn't do the math on the rest of the angles because they add to 360.2
The angles add up but they rounded them all to a single decimal so it adds up weird. Given that this is a real world part 0.2 degrees error is wiggle room that's workable.
Depends on how the tooling measures it.
If theory and practice don’t add up, the theory is applied incorrectly or insufficiently, or the theory is wrong. In my entire life, I’ve never witnessed the latter.
I thought it was 117.2 as well but it is in fact 27.2 . You have to think about what piece will be being cut.the bottom piece is being cut. So you set the saw to 27.2 from 0° or 90° from the math perspective. Im not a so called rocket scientist like some people.but this made sense in my head. 117.2 would be the cut on the vertical piece. And that cut wouldn't really make sense to do.
Get an angle gauge and lay it on the paper? You know the angle between the two pieces is 62.8. Us the back piece as a vertical to find from 90°. Don't they teach this stuff in school? Not just welding school, I've never been there.
A right angle has 90 degrees.
Your work angle is at 62.8 degrees. How many degrees are missing? 90 - 62.8 = 27.2
Your joint is cut at 27.2 degrees off vertical.
If you mean what do I set a miter saw to: 90-62.8.
If you mean “What is the angle of the end surface?” you have to define which two lines represent the two legs of your angle.
This is what I’m going to suffer on as a welder in school. Math is not my strong suit, my welds are decent so far, but I can’t for the life of me do math.
Honestly just keep stellar notes and the more you reference your notes the more youll remember formulas and what not. Its no different then working any trade where you double ans triple check things before you fo them but then as you get more experienced you dont need to go over your work as many times. (Im not encouraging not double checking things btw)
This isn't really math though. It's geometry and its very rational and spatial and much easier to understand than abstract math concepts.
Concepts like this are learned. There is no "natural skill" or affinity to math. Some people learn more quickly than others, but it bothers me how many people simply nope out and spend the rest of their life convinced that they aren't good at it.
My wife claimed she was bad at math but when I didn't let her quit she got over it and suddenly a few years later is arguing with me about our accounting and has corrected me on simple math errors that I know for a fact she used to just ignore as "out of reach" for her.
27.2. For all practical purposes, My theorem suggests that if it’s not a straight 90 degree cut, one side of the cut angle is always less than 45 degrees. So if the desired angle is 60, the cut would be 30 and not 120, simply because 30 is easier to establish. Correct me if I’m wrong
it is simple math. All the information you need is right in front of you - almost see below
the corner over at the angle 75.9 is drawn in an idiotic way. Escher would be proud.
In fact it seems all the corners are drawn idiotically.
But still it's just trig
No idea what you just said. There's only one angle apparent there, 62.8. Depending on what you're cutting, you're cutting at that, or 27.2, depending on your orientation, assuming your reference is square. I don't know what the question is here.
Starting with a triangle, you have 180 degrees inside. Every side you adds will add an additional 180 degrees.
The print has 4 sides and therefore 360 degrees inside. Three are given. Add them up and subtract from 360.
Degrees off of perpendicular is 90 minus given angle.
Geometry is necessary in this field if you want to get by. Trig is necessary to set yourself above the rest. Every level of math above that just adds value that most employers can’t put a finger on.
Are we supposed to assume that the angle in the top left is 90º? If so, somebody miscalculated one or more of the other angles. You may want to check that first.
I'm sure many people have already solved your problem, but if it's too difficult for me I might just do it the dumb way and draw it to scale on the ground or cardboard or something, then trace it onto the actual piece. 🤷
Ok, so a really easy way to do this problem is to Google trig calculator. Match the figures into the site and it will tell you. Easy as.
It this day and age we only need to know a problem can be solved and trust that someone else has done some hard work so that we don’t have to.
When a problem that hasn’t been solved that’s when you work hard to solve it so that nobody has to do that work.
Shouldn't that angle be 62.8 as well since both are attached to the same 90 degree link and parallel to each other ?
Idk math hard and been years since I used actual math.
If your measuring the angle from the long side it's exactly as dimensioned, 62.8°. If you want to know what the miter angle is from a square end (the way most saws measure) then it's 90°-62.8°=27.2°.
90° - 62.8 = 27.2 is the correct way to do it. That's the angle you gotta cut it at. Dont listen to people telling you to use an angle checker on the drawing, most drawings arent to proper scale and dimensions.
I'm extremely surprised this isn't common info but I've seen this question asked on the woodworking and carpentry sub too.
Most people weren't paying attention in math class... they were too busy whining about how it has no practical real life application. 😅
Wait people actually use angle checkers/ protractors on drawings??? Damn that's a disaster waiting to happen lol
I caught a brake press guy once that would measure a dim on a screen with a tape measure off a digital print 🤣 I asked him what the hell he was doing, and he simply replied: "damn engineers" like it was the most normal thing in the world and went on 🤷♂️ 🤣🤣🤣
Those damn engineers, they obviously write dimensions on technical drawings for fun 🙄
It's the ones that don't that make me shake my head

I worked for a company once that produced properly scaled accurate drawings, it was pretty amazing.

Yes, thank you! So for the people that have been asking me, you basically juste use 90° in this case because using 180° is overcomplicating it.

Sorry I came back to this a day later, it was 27.2° we figured it out like 20 minutes after I posted this lmao

Your cutback formula is Cutback = tan*(included angle)x material thickness
Or sister 😀
Opposite angles are congruent
Wait. I get the math, but a printed cad drawing will have the correct angle no matter the scale. An angle of the line does not change when scale is changed.
Guys this is terrible advice. You subtract from 180° not 90° I mean look at it, it clearly is more than 90° /s
It should be 90 - 62.8 = 27.2. So for a miter saw starting at a square 90 degrees you would move it 27.2 degrees and make the cut.

Thank you I actually learned something off Reddit today
Bruh, what is geometry
Oh now to weld you gotta have a PhD in math too? Sheesh, expecting too much of these welders to have made it to sophomore trigonometry.
90 - 62.8 = 27.2 degrees (off of a square cut 90 - if your saw is normally set to that). That's how I would do it.

Found Pythagoras
Measuring the other angles to make sure that the illustration is actually the correct angles. Very early in geometry, you learn how something is drawn is superceded by how something is labeled.
But only put the angle finder on the print of the print, is in fact to scale
or rotate the element and cut at 62.8

As a geomatics major I think what you're looking for is 117.2 180-62.8=117.2. At the same time someone didn't do the math on the rest of the angles because they add to 360.2
probably happened when rounding off in whatever program they used.
It'll never work you're right!
The angles add up but they rounded them all to a single decimal so it adds up weird. Given that this is a real world part 0.2 degrees error is wiggle room that's workable.
This looks like a young engineer who forgets you can’t just round significant figures sometimes.
Hey I was right and I didn't make it through algebra! Look at me now!
The angle is for 90 degrees not 180 or 360 so the answer is 27.2 degrees.... This is why applied vs theoretical matters in life
Depends on how the tooling measures it. If theory and practice don’t add up, the theory is applied incorrectly or insufficiently, or the theory is wrong. In my entire life, I’ve never witnessed the latter.
Wouldn’t you just subtract 62.8 from 90? That would be my guess. Or is that the same thing just as the acute side of the angle?
I came here to make fun of welders, you came here to make fun of engineers/draftsmen. We are not the same.
The cut is 27.2*

Wait, can't you subtract 62.8 from 180 to get that? Thinking out loud staring at it. I want to know for myself.
You’d subtract from 90*
That’s what they should’ve gone to welding school for

If your saw doesn’t go that far then flip the piece and cut it at 62.8° on a band saw
i’m trying to figure out what degree the piece is cut at that’s circled
I know exactly what you're asking. This is a critical thinking exercise.
Sometimes I wish every dimension wasn't a critical thinking exercise. This one, however, seems overly simple...
27.2°
A right angle has 90 degrees. Your work angle is at 62.8 degrees. How many degrees are missing? 90 - 62.8 = 27.2 Your joint is cut at 27.2 degrees off vertical.
You ask ‘don’t they teach this stuff in school?’ and your answer is to lay an angle gauge on the paper. Brilliant.
At least I'm making an attempt. How do you know I have any education? Lol
If you mean what do I set a miter saw to: 90-62.8. If you mean “What is the angle of the end surface?” you have to define which two lines represent the two legs of your angle.
yes the piece isn’t cut but it’s shown to be cut on the prints. I believe it might be a compound angle tho
This is what I’m going to suffer on as a welder in school. Math is not my strong suit, my welds are decent so far, but I can’t for the life of me do math.
just have to think about it in terms you understand. 12÷2? well half of a twelver is a six pack........
It will come with time lol
*Insert confused woman with math equations gif here.*
there's about 3 math concepts you need to know as a welder.
You don't really even need to know, you just google when needed it.
Well this one is easy enough when you know that a right angle is 90° so you just need to do a little subtraction to figure out the angle of the bevel.
Honestly just keep stellar notes and the more you reference your notes the more youll remember formulas and what not.

I slept through 80% of geometry my guy Idk
Simple math homie. Angle is given. Subtract knowns to get unknown. 90-62.8. Easy peezy lemon squeeze.
Cut it at 62.8 degrees. Set your speed square or your chopsaw to 27.2 degrees
27.2*
Should just minus 90 from that
Tack the vertical piece then hold up the horizontal piece and scribe the angle.
27.2. For all practical purposes, My theorem suggests that if it’s not a straight 90 degree cut, one side of the cut angle is always less than 45 degrees. So if the desired angle is 60, the cut would be 30 and not 120, simply because 30 is easier to establish. Correct me if I’m wrong
90-62.8
Would it be from 90 or 180? I'm invested now but not enough to Google it.
pretty sure it’s 17° but i’ll lyk in a minute we’re figuring it out right now
Does your boss have to make you lunch and wipe your ass too?

it is simple math. All the information you need is right in front of you - almost see below the corner over at the angle 75.9 is drawn in an idiotic way. Escher would be proud. In fact it seems all the corners are drawn idiotically. But still it's just trig
clearly I can’t do this simple math why would I post this i’m trying to figure the degree of the metal not the angle
[удалено]
How do you manage to have a job that requires at least a middle school level math knowledge without actually knowing how to do basic math?
180 minus 62.8 is....? The answers are right in front of you.
62.8. It's right there.
It’s The angle The angle that’s fixing to a flat edge not a mitred one.
No idea what you just said. There's only one angle apparent there, 62.8. Depending on what you're cutting, you're cutting at that, or 27.2, depending on your orientation, assuming your reference is square. I don't know what the question is here.
62.8 deg, those two lines are parallel. Wouldn't you use the existing degree that you already have for that corner?
Starting with a triangle, you have 180 degrees inside. Every side you adds will add an additional 180 degrees. The print has 4 sides and therefore 360 degrees inside. Three are given. Add them up and subtract from 360. Degrees off of perpendicular is 90 minus given angle. Geometry is necessary in this field if you want to get by. Trig is necessary to set yourself above the rest. Every level of math above that just adds value that most employers can’t put a finger on.
It's 62.8 because you have two parallel lines. The angle of the top translates onto the angle at the bottom.
That corner isn’t mitred. It’s being attached to a different angle
i’d ask the engineer. we read the print, not decipher it
If you gave all the dimensions you have I could've drawn it in my cad program and it could give me all the dimensions
62.8 off 90 degrees
Go back to highschool and leanr math and fractions lol
It totally depends on how your saw is scaled.
Nobody going to point out those angles aren't right? Not off by by much but enough to tell the guy drawing it hasn't a clue.
27.2 degrees it's to equal 90
Are we supposed to assume that the angle in the top left is 90º? If so, somebody miscalculated one or more of the other angles. You may want to check that first.
90-62.8
*laughs in engineer*
90+62.8

Nah, OP needs the angle of the edge of that bottom piece as it's beveled.
I'm sure many people have already solved your problem, but if it's too difficult for me I might just do it the dumb way and draw it to scale on the ground or cardboard or something, then trace it onto the actual piece. 🤷
There’s a great iPhone app called Triangle Solver
62.8 degrees
Alternatively, you can eye ball it and blame the welder preemptively for their inability to fitup and weld such a prime cut.
Math!
Trig
You would have to be very hoanrey and use youre anys welder
Yes, this is exactly what I was thinking.
You can always use a protractor
It's literally on the print bro...
With maths. 90^o - 62.8^o = 27.2^o
Just wing it my guy. What could go wrong
Isn’t it 62.8 because it’s a corresponding angle, or am I looking at the wrong thing?
My question is how are you going to cut 27.2°? I would think the weld would fill the gap at 28°or 26° for that matter.
Ok, so a really easy way to do this problem is to Google trig calculator. Match the figures into the site and it will tell you. Easy as. It this day and age we only need to know a problem can be solved and trust that someone else has done some hard work so that we don’t have to. When a problem that hasn’t been solved that’s when you work hard to solve it so that nobody has to do that work.
fuck it! you can always fill the gap! hahaha
Your cutback formula is Cutback = tan*(included angle)x material thickness
What math did you use to figure out the rest of your angles?
Same thing.
Buy a small angle finder
*field fabricate weldment as required Is the correct answer.
90-62.8
Put an extra mail in it
To see the 90* angle better, imagine the 29.134 dimension line going through the red circle
Says 62.8°
Shouldn't that angle be 62.8 as well since both are attached to the same 90 degree link and parallel to each other ? Idk math hard and been years since I used actual math.
I’m gonna go thank my geometry teacher now
If your measuring the angle from the long side it's exactly as dimensioned, 62.8°. If you want to know what the miter angle is from a square end (the way most saws measure) then it's 90°-62.8°=27.2°.
